Please merge procfs into the Hurd repository

[Justus Winter]

Dear maintainer :)

please merge procfs (found in [0]) into the main Hurd repository.

0: git://git.sv.gnu.org/hurd/procfs.git

Rationale:

The procfs translator provides a Linux-compatible /proc filesystem.
While there is no standard that defines the /proc filesystem, a lot of
software depends on this.  Having a /proc filesystem thus enables more
software to run on the Hurd.  The procfs has been tested in
Debian/Hurd for quite some time now.  I consider it essential for any
Hurd distribution.

Pros:

Integrating it into the main repository ...

* ... gives it a broader exposure to reviews, cleanups, and static
  analysis.

* ... makes large-scale changes to the Hurd base easier.  The procfs
  translator depends on the API and most likely even internal
  implementational details of the core Hurd libraries.

* ... makes packaging the Hurd easier for Debian/Hurd and any other
  potential distributions.

Thanks for considering,
Justus
